APPLICABILITY: The working range is 4 to 150 ppm (20 to 600 mg/m 3) for a 6-L air sample.
INTERFERENCES: None identified. The method was used in epoxy spray paint operations with no apparent interference from ethylene chloride, toluene, xylene, perchloroethylene and Freon 113 [2]. Alternative columns for this method are 5% FFAP on Chromosorb T (40/60 mesh) packed on stainless steel [2] and a WCOT OV-101 (0.25 µm film thickness) glass capillary [3].
OTHER METHODS: This revises NIOSH Method S365 [4].
